Pierre Souchay	0e907f5aa8	Support for maximum size for Output of checks (#5233) ... * Support for maximum size for Output of checks This PR allows users to limit the size of output produced by checks at the agent and check level. When set at the agent level, it will limit the output for all checks monitored by the agent. When set at the check level, it can override the agent max for a specific check but only if it is lower than the agent max. Default value is 4k, and input must be at least 1.	5 years ago

Aestek	b839f52195	kv: do not trigger watches when setting the same value (#5885) ... If a KVSet is performed but does not update the entry, do not trigger watches for this key. This avoids releasing blocking queries for KV values that did not actually changed.	6 years ago
Matt Keeler	f3d9b999ee	Add tagged addresses for services (#5965) ... This allows addresses to be tagged at the service level similar to what we allow for nodes already. The address translation that can be enabled with the `translate_wan_addrs` config was updated to take these new addresses into account as well.	6 years ago
R.B. Boyer	40336fd353	agent: fix several data races and bugs related to node-local alias checks (#5876) ... The observed bug was that a full restart of a consul datacenter (servers and clients) in conjunction with a restart of a connect-flavored application with bring-your-own-service-registration logic would very frequently cause the envoy sidecar service check to never reflect the aliased service. Over the course of investigation several bugs and unfortunate interactions were corrected: (1) local.CheckState objects were only shallow copied, but the key piece of data that gets read and updated is one of the things not copied (the underlying Check with a Status field). When the stock code was run with the race detector enabled this highly-relevant-to-the-test-scenario field was found to be racy. Changes: a) update the existing Clone method to include the Check field b) copy-on-write when those fields need to change rather than incrementally updating them in place. This made the observed behavior occur slightly less often. (2) If anything about how the runLocal method for node-local alias check logic was ever flawed, there was no fallback option. Those checks are purely edge-triggered and failure to properly notice a single edge transition would leave the alias check incorrect until the next flap of the aliased check. The change was to introduce a fallback timer to act as a control loop to double check the alias check matches the aliased check every minute (borrowing the duration from the non-local alias check logic body). This made the observed behavior eventually go away when it did occur. (3) Originally I thought there were two main actions involved in the data race: A. The act of adding the original check (from disk recovery) and its first health evaluation. B. The act of the HTTP API requests coming in and resetting the local state when re-registering the same services and checks. It took awhile for me to realize that there's a third action at work: C. The goroutines associated with the original check and the later checks. The actual sequence of actions that was causing the bad behavior was that the API actions result in the original check to be removed and re-added _without waiting for the original goroutine to terminate_. This means for brief windows of time during check definition edits there are two goroutines that can be sending updates for the alias check status. In extremely unlikely scenarios the original goroutine sees the aliased check start up in `critical` before being removed but does not get the notification about the nearly immediate update of that check to `passing`. This is interlaced wit the new goroutine coming up, initializing its base case to `passing` from the current state and then listening for new notifications of edge triggers. If the original goroutine "finishes" its update, it then commits one more write into the local state of `critical` and exits leaving the alias check no longer reflecting the underlying check. The correction here is to enforce that the old goroutines must terminate before spawning the new one for alias checks.	6 years ago

R.B. Boyer	cc1aa3f973	acl: adding Roles to Tokens (#5514) ... Roles are named and can express the same bundle of permissions that can currently be assigned to a Token (lists of Policies and Service Identities). The difference with a Role is that it not itself a bearer token, but just another entity that can be tied to a Token. This lets an operator potentially curate a set of smaller reusable Policies and compose them together into reusable Roles, rather than always exploding that same list of Policies on any Token that needs similar permissions. This also refactors the acl replication code to be semi-generic to avoid 3x copypasta.	6 years ago

Matt Keeler	afa1cc98d1	Implement data filtering of some endpoints (#5579) ... Fixes: #4222 # Data Filtering This PR will implement filtering for the following endpoints: ## Supported HTTP Endpoints - `/agent/checks` - `/agent/services` - `/catalog/nodes` - `/catalog/service/:service` - `/catalog/connect/:service` - `/catalog/node/:node` - `/health/node/:node` - `/health/checks/:service` - `/health/service/:service` - `/health/connect/:service` - `/health/state/:state` - `/internal/ui/nodes` - `/internal/ui/services` More can be added going forward and any endpoint which is used to list some data is a good candidate. ## Usage When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of: ``` <selector> == <value> <selector> != <value> <value> in <selector> <value> not in <selector> <selector> contains <value> <selector> not contains <value> <selector> is empty <selector> is not empty not <other expression> <expression 1> and <expression 2> <expression 1> or <expression 2> ``` Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library ## Other changes Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.	6 years ago

Matt Keeler	18b29c45c4	New ACLs (#4791) ... This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week. Description At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers. On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though. Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though. All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management. Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are: A server running the new system must still support other clients using the legacy system. A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system. The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode. So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.	6 years ago
Rebecca Zanzig	34e5516834	Support multiple tags for health and catalog http api endpoints (#4717) ... * Support multiple tags for health and catalog api endpoints Fixes #1781. Adds a `ServiceTags` field to the ServiceSpecificRequest to support multiple tags, updates the filter logic in the catalog store, and propagates these change through to the health and catalog endpoints. Note: Leaves `ServiceTag` in the struct, since it is being used as part of the DNS lookup, which in turn uses the health check. * Update the api package to support multiple tags Includes additional tests. * Update new tests to use the `require` library * Update HealthConnect check after a bad merge	6 years ago
Pierre Souchay	51b33ef015	[Performance On Large clusters] Reduce updates on large services (#4720) ... * [Performance On Large clusters] Checks do update services/nodes only when really modified to avoid too many updates on very large clusters In a large cluster, when having a few thousands of nodes, the anti-entropy mechanism performs lots of changes (several per seconds) while there is no real change. This patch wants to improve this in order to increase Consul scalability when using many blocking requests on health for instance. * [Performance for large clusters] Only updates index of service if service is really modified * [Performance for large clusters] Only updates index of nodes if node is really modified * Added comments / ensure IsSame() has clear semantics * Avoid having modified boolean, return nil directly if stutures are Same * Fixed unstable unit tests TestLeader_ChangeServerID * Rewrite TestNode_IsSame() for better readability as suggested by @banks * Rename ServiceNode.IsSame() into IsSameService() + added unit tests * Do not duplicate TestStructs_ServiceNode_Conversions() and increase test coverage of IsSameService * Clearer documentation in IsSameService * Take into account ServiceProxy into ServiceNode.IsSameService() * Fixed IsSameService() with all new structures	6 years ago

Paul Banks	b83bbf248c	Add Proxy Upstreams to Service Definition (#4639) ... * Refactor Service Definition ProxyDestination. This includes: - Refactoring all internal structs used - Updated tests for both deprecated and new input for: - Agent Services endpoint response - Agent Service endpoint response - Agent Register endpoint - Unmanaged deprecated field - Unmanaged new fields - Managed deprecated upstreams - Managed new - Catalog Register - Unmanaged deprecated field - Unmanaged new fields - Managed deprecated upstreams - Managed new - Catalog Services endpoint response - Catalog Node endpoint response - Catalog Service endpoint response - Updated API tests for all of the above too (both deprecated and new forms of register) TODO: - config package changes for on-disk service definitions - proxy config endpoint - built-in proxy support for new fields * Agent proxy config endpoint updated with upstreams * Config file changes for upstreams. * Add upstream opaque config and update all tests to ensure it works everywhere. * Built in proxy working with new Upstreams config * Command fixes and deprecations * Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts... TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct. * Fix translated keys in API registration. ≈ * Fixes from docs - omit some empty undocumented fields in API - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally. * Documentation updates for Upstreams in service definition * Fixes for tests broken by many refactors. * Enable travis on f-connect branch in this branch too. * Add consistent Deprecation comments to ProxyDestination uses * Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs	6 years ago
Paul Banks	88388d760d	Support Agent Caching for Service Discovery Results (#4541) ... * Add cache types for catalog/services and health/services and basic test that caching works * Support non-blocking cache types with Cache-Control semantics. * Update API docs to include caching info for every endpoint. * Comment updates per PR feedback. * Add note on caching to the 10,000 foot view on the architecture page to make the new data path more clear. * Document prepared query staleness quirk and force all background requests to AllowStale so we can spread service discovery load across servers.	6 years ago
Pierre Souchay	eddcf228ea	Implementation of Weights Data structures (#4468) ... * Implementation of Weights Data structures Adding this datastructure will allow us to resolve the issues #1088 and #4198 This new structure defaults to values: ``` { Passing: 1, Warning: 0 } ``` Which means, use weight of 0 for a Service in Warning State while use Weight 1 for a Healthy Service. Thus it remains compatible with previous Consul versions. * Implemented weights for DNS SRV Records * DNS properly support agents with weight support while server does not (backwards compatibility) * Use Warning value of Weights of 1 by default When using DNS interface with only_passing = false, all nodes with non-Critical healthcheck used to have a weight value of 1. While having weight.Warning = 0 as default value, this is probably a bad idea as it breaks ascending compatibility. Thus, we put a default value of 1 to be consistent with existing behaviour. * Added documentation for new weight field in service description * Better documentation about weights as suggested by @banks * Return weight = 1 for unknown Check states as suggested by @banks * Fixed typo (of -> or) in error message as requested by @mkeeler * Fixed unstable unit test TestRetryJoin * Fixed unstable tests * Fixed wrong Fatalf format in `testrpc/wait.go` * Added notes regarding DNS SRV lookup limitations regarding number of instances * Documentation fixes and clarification regarding SRV records with weights as requested by @banks * Rephrase docs	6 years ago
